This course teaches simple reasoning techniques for complex phenomena: divide and conquer, dimensional analysis, extreme cases, continuity, scaling, successive approximation, balancing, cheap calculus, and symmetry. Applications are drawn from the physical and biological sciences, mathematics, and engineering. Examples include bird and machine flight, neuron biophysics, weather, prime numbers, and animal locomotion. Emphasis is on low-cost experiments to test ideas and on fostering curiosity about phenomena in the world.

This is a Web-based story of three children who venture out to find their great-grandfather's treasure box that was lost in the remote state of Alaska. Using simple terminology, the story integrates complex Earth and Space science concepts, such as the formation of gold deposits and the operation of satellites. The children model creative thinking, acquire and interpret radar images, plan a treasure hunt, work systematically, and learn about Alaska. They also exhibit the successes and setbacks of actual research. The story provides opportunities for readers to engage in coloring activities, model building, unit conversions, and math calculations. Additionally, readers can interactively view an image from different heights and compare the size of Alaska to other US states.
